The New Year is approaching, and those who have been busy for a year have begun to rush home one after another.
Chen Yang spent a day helping Wu Jingjing buy New Year's goods and delivered them to Wu Xuan and Ling Lan.
"Chen Yang, why not let Zhigang bring your parents here to celebrate the New Year. They are all together and lively." Ling Lan said to Chen Yang with some reluctance.
After such a long time of contact and observation, in her heart, she had long recognized Chen Yang and regarded him as her grandson-in-law.ъìqυgΕtv.℃ǒΜ
"My parents are used to being in their hometown. When they have the chance, they will take them over." Chen Yang said with a smile.
"Okay." Ling Lan felt a little disappointed.
"Grandma! I think...I want to take Jingjing home with me." Chen Yang said embarrassedly.
"Take Jingjing home?"
Hearing this, Ling Lan was slightly stunned, then looked at Wu Xuan, but found that the old man was looking outside, pretending to be confused.
In the kitchen, Wu Jingjing's face turned red like a ripe red apple.
...
Chen Yang didn't know how he came out of Wu Xuan's house. Anyway, after he said those words, he felt that his mind was blank, he could not remember anything, and could not hear anything.
Wu Jingjing looked at the big boy who looked a little stupid at the moment and couldn't help but feel a little funny: "You face so many experts and professors, face Minister Sun, Minister He, face General Xu, General Lu and others.
When I was not seeing you like this, what's wrong with you now?"
"I...I'm a little empty." Chen Yang said with a red face.
Wu Jingjing supported Chen Yang with gentleness in her eyes.
She had dreamed of accepting confessions countless times before, but never once was like this now.
"Aren't you afraid that I won't agree? It's ugly to you in public?" Wu Jingjing asked Chen Yang.
"Not afraid! If you don't agree, I'll ask for it again."
"Don't agree yet?"
"Then I won't go back this year, I will do nothing, I will be there every day, and I will wait for you until you agree."
Wu Jingjing heard this and curled her lips, then said dissatisfiedly: "If you do that, don't talk about others, I'm afraid my grandfather will not let me go. You know I won't be like this, but you still say these fools.
I."
"Hehe..." Chen Yang smiled as if he had succeeded in his plan.
One day later!
Chen Yang took Wu Jingjing to his hometown in Yuzhou by high-speed rail.
"Professor Chen, we are ordered to send you home." The train chief Fangzhen came over and said with a smile to Chen Yang.
"Is the whole carriage a little waste by myself?" Chen Yang couldn't help but say to the conductor with some embarrassment.
Now, it is the peak period of the Spring Festival travel rush. Isn’t it a bit too luxurious to own a car?
Chen Yang felt a little sad.
"It's not the entire car, but the entire car. You are the only passenger. Our train will only reach the train directly, so it won't be wasted too much." said the conductor.
“…”
"If you have any questions, you can call me anytime."
"Okay, thank you." Chen Yang responded with a smile.
Chen Yang couldn't help but sigh: "Our travel efficiency is still too low. Every year during the Spring Festival travel rush, it is a major mobilization, striving to improve in the future so that every wanderer who returns home can sit home safely and steadily!
Don’t worry about not being able to buy tickets, no need to be crowded anymore!”
"Professor Chen, are you preparing to develop a train?" Luo Tianchen, who knew Chen Yang's temperament, couldn't help but ask with some anticipation.
Although there are more private cars now, once the Spring Festival travel rush is at its peak, people will follow the crowd on the road, and what they really rely on is railway transportation.
"It's not considered R&D, I just have some ideas and want to improve it." Chen Yang said.
"Forget it! Let's start doing it now. I'm idle."
"If I had known you would be like this, I had already prepared the computer projector for you." Wu Jingjing said.
"Superconducting magnetic levitation train." Chen Yang then mobilized all the train information.
"Magnetic levitation trains have never been a reality, mainly because they cannot be obtained at room temperature superconducting materials. Now the abandoned pressure conditions are not raised, and the maximum temperature is 250k, which is minus 23 degrees."
"It has been a great progress from almost absolute zero to minus 23 degrees Celsius, but this is still a great challenge for the earth's room temperature environment."
Afterwards, Chen Yang closed his eyes directly.
Once again, I connected the system and entered the library of the future in my mind.
"Is there any room temperature superconductor?" Chen Yang asked directly.
[Fatal temperature superconducting was realized twenty years ago. Superconducting can be realized using graphene, but what follows is ultra-high pressure! Normal atmospheric pressure cannot be achieved at all. The host should be looking for normal temperature and normal pressure.
Superconductor under.]
"Well, right, it is superconducting substances in normal temperature and pressure environments, such as through specific atomic combinations, to achieve atomic arrangement under cold or high pressure, allowing electrons to pass quickly without having to go with the nucleus or non-free electrons inside the metal.
Collision occurs, and "friction" produces resistance loss." Chen Yang said.
[The host can go to the seventh zone organic matter collection, one of which may meet your needs.] The system said to Chen Yang.
"What? Organic substances?" Chen Yang was a little stunned!
Before, the substances exposed to them were all metals or metal oxides. Although some people can achieve superconductivity by studying organic matter or organic salts, due to the limitations of special materials, the critical temperature of those superconducting materials is quite similar.
Lower is lower than the current known metals or metal oxides, and the conditions are more harsh. There is no way to break through the limit of normal temperature superconducting on organic matter or organic salts.
However, Chen Yang then gradually walked to that place according to the system's prompts. Sure enough, according to the system's prompts, he found a book on the preparation of superconducting substances in it, which was 2311 years!
"It took 200 years from the first discovery of mercury superconducting in 1911 to the final completion of superconducting materials!"
Then, Chen Yang opened the content without hesitation.
After watching it, Chen Yang was stunned for a long time.
It turns out that this material is not a simple organic material, but a metal-organic composite material! Even those metal oxides contain 8 types. Each material has undergone special treatment. All the processes add up to the fullest.
There are as many as 188, and these are the main production processes, not those auxiliary processing processes.
Then, Chen Yang began to sort it out.
Slap sex!
The speed is fast and the entire keyboard is almost broken.
Wu Jingjing silently closed the door for him, while Luo Tianchen sat at the door to prevent anyone from disturbing him.
The knock lasted for more than 2 hours before it was completed.
When he typing the last keyboard, Chen Yang's face flashed with relaxation and pleasure.
